ROLLER-SCREENFOR CAR-WINDOWS.

SPECIFICATION formingpart of Letters Patent N 0. 714,362, dated November 25, 1902.

I Applioationfiled September 4, 1902. SerialNo. 122,061. (No model.)

T0 on whom it may concern:

Be it known that I, FRANK A. CARPENTER, a citizen of the United States, residing at Washington, in the District of Columbia, have inhas special reference to the application of roller-screens to car-windows for the protecdiscomfort produced by cinders from the locomotive-engine entering open windows, and consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a front elevation of a window in closed position; Fig. 2, a like View showing the window raised and a screen in position belowthe window; Fig. 3, a like view, partly in section, to show the means for securing the screen to the window; Fig. 4, a vertical transverse section on line 4 4, Fig. 3; and Fig.5, an enlarged detail view showing the means for securing the screen to the window.

Reference being had to the drawings and the designating characters thereon, 1 indicates a Window-sash; 2 2, the vertical sides of i i the casing; 3 3, the facing on the sides of the vided with a spring 12 for winding the screen..

On the lower edge of bottom rail of the sash is a metallioshoe or bar 13, having slots 14 14 for the reception of locking members on the screen, and inclosed in the sash-rail are oppositely-arranged bolts 15 16, longitudinally movable in bearings 17 18, and on each of said bolts between the bearings 17 18 is a coiled spring 19, one end of which bears against a pin 20, while the opposite end of spring bears against the outer bearings 17 to hold the bolt in engagement with the shoulder or catch 21 on each locking member 22, which members are secured to a metallic bar 23 on the upper end ofthe screen 11. The inner ends of the bolts 15 and 16 are provided with upwardlycurved arms 24, which enter the opening or recessed pocket 25 in the handle 26 for raising the window and are drawn toward each other to release the bolts from the locking members 22 when it is desired to raise the window without raising the screen. non of passengers from the annoyance and g The sash is provided with the usual springcatch 27, which engages the stop 28 to support the window in raised position.

The normal position of the bolts 15 16 is in engagement with the shoulders 21 on the locking members 22, so that as a passenger raises a window provided with my screen the screen is drawn up with the window and serves to prevent the entrance of cinder-s or other obopening unobstructed by the screen, the bolts 15 16 are drawn toward each other, and thus releasing the shoulders or catches 21, when the window can be raised without drawing the screen up with it; but when the window is closed the locking members 22 automatically engage the bolts 15 16 and place the screen in condition to be raised with the window.

Having thus fully described my invention, what I claim is r 1. A window-sash having slots in the lower edge of the bottom rail of the sash, a handle in said bottom rail for raising the sash and having an opening or recessed pocket therein, and a locking device composed of oppositelyarranged spring-controlled bolts contained in said rail and whose adjacent inner ends are in the opening or pocket of saidhandle; in combination with a roller-screen having a transverse bar onits upper end provided with projecting members engaging said slots and said locking device.

2. Awindow-sash havinga metallic shoeon the lower edge of the bottom rail provided with slots, a handle in said bottom rail havvided with projecting members engaging said ing an opening 01' recessed pocket therein, slots and said bolts. 10 and oppositelyarranged spring controlled In testimony whereof I affix my signature horizontal bolts contained in said rail and in presence of two witnesses.

whose inner and adjacent ends are provided FRANK A. CARPENTER. with curved arms contained in the pocket of Witnesses:
